Earthquakes far off the coast on Reykjanes ridge

Yesterday (30. January 2023) had two earthquakes with magnitude Mw3,2 far off the coast on the Reykjanes ridge. Only one smaller earthquake was detected. Distance from the SIL network makes detection of smaller earthquakes is impossible or really difficult.

Besides this earthquake activity, it remains quiet in Iceland. Bad weather has also been blocking detection of earthquake activity for the last two weeks.

Flood risk in Iceland on 20 and 21. January 2023 because of sudden warming after long time period of freezing weather

I normally write about earthquakes and volcanoes in Iceland. This is a little change from that. Starting tomorrow (20 and 21. January 2023) there’s a flood risk in all of Iceland as there’s going to be a sudden warm and there’s a lot of snow and rivers have frozen over in last few weeks in Iceland. There’s a lot of flood expected all over Iceland, along with risk of avalanches from mountains and other snow and rain and water related floods. Travelling might get risky or impossible because of flooding and melting snow.

Earthquake swarm in Krýsuvík-Trölladyngja volcano

Today (21. December 2022) an earthquake with magnitude of Mw3,4 took place in Krýsuvík-Trölladyngja volcano. This earthquake is because of inflation in Fagradalsfjall volcano. This possibly means that the inflation in Fagradalsfjall volcano is reaching critical point and might result in a eruption soon, when that point is reached is difficult to know.

Earthquake swarm 3 km north of Grindavík town

Today (19. December 2022) and yesterday (18. December 2022) an earthquake swarm took place 3 km north of Grindavík town in the Reykjanes volcano. Largest earthquake had a magnitude of Mw2,9 and was felt in Grindavík. Earthquakes with magnitude Mw2,0 are felt in Grindavík, possibly even smaller earthquakes. At the writing of this article, this earthquake swarm is ongoing but weather is blocking almost all of the automatic earthquake detection.
